Correct Answer: C

Rationale: Cleaning a wound from the center outwards is the most appropriate action as it helps prevent the spread of infection. Choice A is incorrect as phenol solutions can be harmful to the wound and delay healing. Choice B may increase the risk of infection as warmth can promote bacterial growth. Choice D is unnecessary unless there are signs of infection present.

Correct Answer: B

Rationale: The correct answer is B: Ensure the blood type is compatible with the client. This is the most crucial step in preparing for a blood transfusion to prevent severe transfusion reactions. Checking the client for a fever (Choice A) is important but not the most critical step. Administering blood via IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow drip. Warming the blood to body temperature (Choice D) is not a standard practice and can lead to hemolysis, making it an incorrect choice.

Correct Answer: B

Rationale: Assessing the client's gait for steadiness is the most appropriate action to ensure the safety of a client with dementia while walking. This allows the nurse to identify any issues that may increase the risk of falls or accidents. Administering PRN haloperidol or lorazepam is not indicated as the first-line approach in managing wandering behavior and can have adverse effects like increased risk of falls, confusion, or oversedation. Restraint use should be avoided whenever possible, as it can lead to physical and psychological harm to the client.

Correct Answer: A

Rationale: The correct answer is A: Staphylococcus aureus infections, including MRSA. Severe infections like MRSA are required to be reported to the health department as they pose a significant public health risk. Choices B, C, and D are incorrect because severe flu-like symptoms, common colds, and non-severe respiratory infections, and only contagious diseases like meningitis do not fall under the category of infectious diseases that must be reported to the health department.

Correct Answer: B

Rationale: The correct answer is B because prolonged use of corticosteroids is a known risk factor for infections. Choice A is incorrect because frequent hand washing actually helps prevent infections. Choice C is incorrect as patient interaction is essential in healthcare but should be done following proper infection control measures. Choice D is also incorrect as restricting client movement is not a standard practice to prevent contamination.
